COIL-WINDER.

Application filed November 8, 1919.

To all whom it may concern:

Be it known that I, LOUIS F. S'rRA'rroN, a citizen of the United States, and a resident of Charlotte, county of Mecklenburg, tate of North Carolina, have invented a new and useful Coil-finder, of which the following is a full, clear, and exact description.

The present invention relates to a coil winder and has reference more particularly to a device for winding coils of wire and the like.

The primary object of the invention is to provide a coil winder by which wire or the like may be wound in coils of various sizes and designs.

A further object of the invention is to provide a comparatively cheap and simple device which is capable of various adjustments and on which wire or the like may be coiled in a most convenient and practical manner.

Further objects of the invention will appear upon reference to the accompanying drawings, and the following detailed description, the novelty being particularly pointed out in the subjoined claims.

Figure 1 is a top plan view of the device assembled and ready for use.

Fig. 2 is a front elevation showing the frame mounting partly in section, and with one of the frame members shown in dotted lines in a position which may be realized by the adjustment of one of the frame members.

Fig. 3 is a side elevation looking at the front of the device and with a part of the frame removed. 1

Fig. 4 is a sectional view on the line 1-4 of Fig. 2.

Fig. 5 is a sectional view. on the line 55' of Fig. 2.

Fig. 6 is a detailed view of a part of the removable frame looking at the inner face of the same, and

Fig. 7 is a detailed view parallel in section of the mounting for .the removable part of the frame.

According to the preferred embodiment ofthe invention the coil winder preferably comprises a bearing support 1, in which the spindle 2 is mounted co-axially with the elongated sleeve 3. The sleeve 3 terminates in a block ff which is provided with parallel recesses in its face made to receive the frame member 5. The spindle 2 extends through Specification of Letters Patent.

the block 1 and the frame member 5 terminates in a pointed end 6.

As thus provided it will be seen that the frame member 5, the sleeve 3 and the spindle 2 are all fixed as one and capable of rotation in the bearing support 1. The end of the spindle 2 is made to receive the removable or opposite frame member 7 which 1s adapted to be coaxially mounted with themember 5 so that the same may be supported parallel with the member 5 and spaced in confronting relation relative thereto.

The mounting for this removable member 7 preferably comprises a block 8 which is presented outwardly from the face of the member and provided with an axial bore made to receive the end of the spindle. To normally prevent rotary or axial sliding movement of the member 7 on the spindle. the block 8 is provided with a transverse re cess in which is slidably mounted the bifurcated yoke 9, the bifurcation of which is adapted to straddle the spindle with a tongue 10 received in an annular recess 11, on the end of the spindle, and with a pin 12 seated in a slot 13. Disposed between the seat 14 and the end of the recess in the outwardly presented part of the member 9 is a spring 15 whose normal tendency is to raise the member 9 with the tongue 10 presented in the recess 11 of the spindle and with the pin 12 confined in the recess 13. The tongue 10, of course when engaged in the recess, 11 will prevent any axial sliding movement and the pin when held in the recess 13 will prevent any rotary movement of the member.

When pressure is brought to bear on the member 9 the tongue 10 will be removed from the recess 11, likewise the pin 9 will be disengaged from the opening 13, whereupon the frame member 7 which is supported in the block 8, the same as the member 5 is supported in the block 4, may be withdrawn from the spindle. Both the frame members 5 and 7 are provided with elongated longitudi nal slots 16 which extend from end to end of the members. Slidably mounted in the recess 16 of the member 5 are posts 17 which extend through the clamps 18 arranged on opposite sides of the member with locking means, such as the wing nuts 19 threaded on the end of the posts for maintaining them clamped in any longitudinal adjustment and relative to the slot 16 in the member 5. The slot 16 in the opposite member 7 is adapted to support abutment clamps 20 which are also provided with wing nuts 21 threaded in the end of the bolts 22 for clamping the abutments in any desired adjustment in the slot.

The inner faces of the abutments 20 are slotted as at 23 and made to receive the ends of the posts 17. These abutment clamps are always moved on the member 7 whenever the posts 17 are moved on the member 5 so that the ends of the posts will always be received in the slots 23. Slidably mounted in the elongated slots 16 of the members 5 and 7 are the transverse frame members 24: and 25. These members of which there are two pairs are slidably mounted in the slots by means of the clamps 26 and 27. These clamps comprise bolts 28 and 29 which are counter-sunk in the face of the members 24 and 25 respectively with their ends extending through the recess and terminating with the wing nuts 30 and 31 received on the threaded ends thereof.

It will be thus seen that the transverse members 24 and 25 may be longitudinally adjusted relative to the first mentioned members 5 and 7. Furthermore by loosening the bolts 28 and 29 it will relieve the clamping action of the clamps, and an angular adjustment of the members 21 and 25 may also be had, (see for instance position illustrated in dotted lines in Fig. 2). As stated there are two pairs of these transverse members 24 and 25, and one of each pair, namely 24:, is also provided with an elongated longitudinal slot 32. slidably mounted in these slots 32 are the posts 33 which are clamped therein in very much the same manner as the posts 17 are clamped in the slots 16 of the member 5 with the exception that rests, comprising the plates 34- are arranged to support the posts 33 on the inner faces of the members 24. These supports are maintained in cooperative relation with the posts by the screws 35. The ends of the posts 33 abut against the inner faces of the member 25. The clamps for the posts 33 comprise the wing nuts 36 which are threaded on the ends of the posts 33 and bear against the clamp lock 37.

It will of course be seen that by relieving the effect of the clamps from the posts 33 they may be longitudinally adjusted in the slots 32. Therefore not only are the posts 33 adjusted relative to the transverse frame members 24- and 25 but these members themselves are adjusted relative to the first mentioned frame members 5 and 7 and in this way the position of the-posts 17 and the posts 33 may be adjusted relative to each other consequently changing the shape and dimensions of the coil wound around the posts. A suitable handle 38 may be used to revolve the' frame. .By relieving the clamps 26 and 27 either of the transverse frame members 24, or the members 25 may be selectively and angularly adjusted as referred to with reference to Fig. 2. The

frame members are graduated as best shown in Fig. 3 so that the dimensions of the coil wound around the posts may be accurately determined. 7

Having thus described my invention what I claim as new and desire to secure by Letters Patent is as follows 1. A coil winder comprising a revoluble frame, comprising frame strips and cross strips, a plurality of posts spaced apart thereon and around which the coil is formed, means for slidably adjusting the positions of said posts relative to each other, and means for selectively and angularly adjusting the position of said cross strips relative to each other and the frame strips.
